Oxidation takes place at the anode and reduction takes place at the cathode.

Anode- Oxidation half-cell: Cu → Cu²⁺ + 2e^-

Cathode- Reduction half-cell: 2Ag⁺ + 2e^- →2Ag

Overall reaction : Cu + 2Ag⁺→ Cu²⁺ + 2Ag

By convention while representing a galvanic cell, the following steps have to be followed:

1) The anode is always placed to the left and cathode to the right

2) The metal and electrolyte of the same half-cell are separated by a vertical line

3) A double vertical line which represents the salt bridge is placed in between the two half-cells to complete the notation of the galvanic cell.

Galvanic cell notation: Cu(s)| Cu²⁺(aq)|| Ag⁺(aq)| Ag(s)
